- a main body 1 mounted within the interior of the main body 1 is an internal combustion engine, not shown, of a small size and suitable type serving as a power source which can be controlled by operating a throttle lever 2 connected to one side of the main body 1.
- a blower 3 is mounted within the main body 1 and includes an impeller 4 connected to the internal combustion engine and driven thereby for rotation to draw air by suction through a central suction port 5 and discharge same into a volute casing 6 after pressurizing same.
- the volute casing 6 has an outlet end 7 located on a side of the main body 1 opposite the side on which the throttle lever 2 is located and having a curved tube 8 removably connected thereto, so that the pressurized air can be ejected through a forward end of the curved tube 8.
- the main body 1 has an upper surface 9 on which a liquid tank 10 is removably mounted.
- the tank 10 has a bottom wall 11 which is planar and has secured to its outer surface a seat-like member 12 which is maintained in close contact with the upper surface 9 of the main body 1.
- the seat-like member 12 is formed integrally on its undersurface with four downwardly projecting portions 13 of which two are located at opposite sides of a forward end portion of the seat-like member 12 and the other two are located on opposite sides of a rearward end portion thereof, so as to hold an upper portion of the main body 1 between the downwardly projecting portions 13 at the forward and rearward end portions of the seat-like member 12 (see FIG. 2).
- Two pairs of through holes extending from a forward end of the main body 1 to a rearward end thereof are formed in the downwardly projecting portions 13 of the seat-like member 12 and the upper portion of the main body 1.
- a pair of manually-openable bolts 15 are each inserted in one of the two pairs of through holes and threadably engage each of internally threaded holes 16 formed in the downwardly projecting portions 13 located in the rearward end portion of the seat-like member 12, to thereby secured the seat-like member 12 and hence the liquid tank 10 to the main body 1.
- a rubber sleeve 17 is interposed between the downwardly projecting portions 13 at the forward and rearward end portions of the seat-like member 12, and the bolts 15 extend through the rubber sleeve 17 to ensure that the downwardly projecting portions 13 are firmly secured in place.
- a curved air extracting line 18 which is secured to the upper portion of the main body 1 has an inlet end opening in a volute casing 6 of the blower 3 in such a manner that its open end faces a upstream end of an air current flowing therethrough and an outlet end terminating at an annular rubber seat 19 secured to the planar upper surface 9 of the main body 1.
- a tubular air introducing member 20 is secured to a bottom wall 11 of the liquid tank 10 in a position in which it is maintained in alignment with the outlet end of the air extracting line 18.
- the tubular air introducing member 20 which extends through the bottom wall 11 of the liquid tank 10 is formed at its outer end with an annular flange 21 which cooperates with a nut 22 mounted on the member 20 inside the tank 10 to clamp against the bottom wall 11 with a seal being interposed therebetween while an end face of the annular flange 21 airtightly presses against the annular rubber seat 19.
- the air introducing member 20 is airtightly connected at its inner end to one end of a flexible air line 23 of a length having a reserve which extends upwardly through the tank 10 and opens in an open space in an upper portion thereof at an opposite end which is supported by a lid 24 for closing a liquid supplying port of the liquid tank 10.
- the seat-like member 12 is formed with a cutout to enable the annular rubber seat 19 and the annular flange 21 of the tubular air introducing member 20 to be suitably connected together in airtight sealing relation.
- the pressurized liquid chemical agent 25 is supplied from the liquid tank 10 to a spray nozzle, not shown, via a liquid feed line 26 connected to a lower portion of the liquid tank 10, so that the liquid chemical agent 25 can be sprayed in atomized particles through the spray nozzle and scattered by the current of air ejected from the blower 3 through the curved tube 8.
- the two bolts 15 are withdrawn from the holes formed in the main body 1 and the downwardly projecting portions 13 of the seat-like member 12, and then the liquid tank 10 is removed from the main body 1. Thereafter, a grip member 27 is placed on the upper surface 9 of the main body 1, as shown in FIG. 3, and the two bolts 15 are inserted in the holes and threadably engage the thread holes 16 in the same manner as described previously. Portions of the grip member 27 at which it is secured to the main body 1 by the bolts 15 are similar to the portions of the liquid tank 10 at which it is secured to the main body 1.
- the grip member 27 if formed at its underside with downwardly projecting portions which are formed with holes for the bolts 15 to extend therethrough, to securedly connect the grip member 27 to the main body 1.
- the grip member 27 includes a handle 28 formed integrally therewith at its upper portion, to enable the operator to grip the handle 28 and move the blower/spray device from one place to another.
- the grip member 27 is formed at its underside with a closing surface portion 29 positioned against the annular rubber seat 19 secured to the upper surface 9 of the main body 1 to thereby close the outlet end of the air extracting line 18.
- the closing surface portion 29 is positively brought into pressing engagement with the annular rubber seat 19 when the grip member 27 is placed in a predetermined position on the upper surface 9 of the main body 1, so as to thereby prevent the pressurized air in the volute casing 6 of the blower 3 from leaking to outside through the air extracting line 18.
